On a general commute into work and back my consumption shot up by about 4 MPG by turning off the air con, heated seats, rear window, subwoofer in the boot and using cruise control to ensure a smooth and light tough on the accelerator.  So, yes all these goodies demand lecky which in turn causes the engine to work that bit harder (he said having zero clue about it at all really)..... :lipsrsealed:

Also didnt help me getting revo, having a fight with the dealer and demanding he remove it...since then my mpg has been pants...I reckon he tweaked my settings somehow,....good mind to go to another revo guy and ask them to verify......that said, may just either take to VW for ecu reflash to standard OR go Bluefin and pump up the volume....why am I waffling lol...this thread is nothing to do with all that!  :laugh: Still beats talking to the wife on Valentines day eh! :kiss:

The only good thing about fuel is, that when it's really cold you get more fuel for your tank due to it's denser than on hotter day's so I'm told :undecided:

Its a liquid, so wont really make that much difference, if any.

However, the air outside is denser when cold motors in general but particuarly turbocharged ones respond better to denser intake air. You will see higher bhp output from colder/denser air.

MPG will normally go down in cold weather, which I think is down to a fair few things. One of which being the fact that the automatic choke will stay on for longer due to the engine taking longer to get up to temperature.

It says in the owner's manual that fuel consumption is increased during cold weather. There's a graph and everything.

Check your tyre pressures. Checked mine using an analogue guage and they were at 30psi instead of 37psi! All four of them! And they had been checked a few weeks back at Tescos. Went and bought a footpump from Halfrauds now.

I've been getting poor mpg for a couple of weeks now. Normally I'd get 30-35 mpg on the commute to work (nice and steady, 6th gear, little throttle). For the past two weeks, Haven't gotten better than 29mpg.

Why a foot pump as the ones that are powered from your cig lighter socket aren't expensive.
